Answer:
Step-by-step explanation:
Given that a business school reports that 37% of its graduate students have an engineering background, and 24% have a social science background
In addition, the university’s annual report indicates that the students in its business school comprise 18% of the total graduate population at the entire university.
a) What is the probability that a randomly chosen university graduate student student is a business school student with a social science background?
Prob for business school student and social science background
=
(b) What is the probability that a randomly chosen university graduate student is neither a business school student with an engineering background nor a business school student with a social science background?
Prob neither business schools student with an engineering background nor a business school student with a social science background

Answer:
a. No
b. Stratified Random Sampling was used
Step-by-step explanation:
a. No, I don't think the group was using a simple random sampling SRS ,because statistician students takes a survey of 200 samples and the sample was distributed into different categories , which is unlikely to happen in simple random sampling.
b. I think stratified random sampling was used because this type of sampling requires the population strata to be made.
In the question, the population is 200 and it is distributed into 4 strata which are :50 first-year students, 50 sophomores, 50 juniors, and 50 seniors.
Thus, the stratified random sampling was used
-9-16m=7
-16m=7+9
-16m=16
-m=1
m=-1
This would be a scalene triangle, because all of the sides are different lengths.
The correct answer is C.
